Establishing of an Early Warming System of Premature Ovarian Insufficiency

Premature ovarian insufficiency (POI) is a clinical syndrome defined by loss of ovarian activity before the age of 40 years. The POI guideline development group of ESHRE recommends the following diagnostic criteria: oligo/ amenorrhea for at least 4 months and an elevated follicle stimulating hormone (FSH) level 25 mIU/mL on ...

Phase N/A

Prospective Genetic Study in Patients With Ovarian Insufficiency

The cause of ovarian insufficiency and decline in ovarian reserve are not clear, but most researchers think the probable causes are mainly three aspects: chromosomal abnormalities, genetic factors and autoimmune diseasesBut the majority of patients with normal chromosome karyotype analysis. The screening of pathogenic genes in patients with normal karyotype ...

Effect of Testosterone Treatment on Embryo Quality

At CHR the investigators have been using DHEA supplementation to improve ovarian response to ovulation induction for in vitro fertilization for about five years (Barad, Brill et al. 2007; Barad, Weghofer et al .2009; Gleicher, Ryan et al. 2009; Gleicher, Weghofer et al. 2010; Gleicher and Barad 2011). Our views ...

UTHealth Turner Syndrome Research Registry

Turner syndrome (TS) is a common chromosomal disorder that affects approximately 1 in 2500 live female births. Complete or partial monosomy of one of the X chromosomes in a female is associated with various congenital heart defects (CHDs), which include aortic dilatation, coarctation of aorta and BAV. Congenital cardiovascular defects ...

The Clinical Study of Sex Chromosome Variants

Infertility is a disease that affects approximately 10% of couples world-wide. Causes of infertility are varied and include age-related decline in fecundity, other causes of ovulatory dysfunction, tubal and pelvic pathology, male causes, idiopathic, and multifactorial. The underlying genetic causes of infertility are incompletely understood. The purpose of this study ...

Treatment With HMG-COA Reductase Inhibitor of Growth and Bone Abnormalities in Children With Noonan Syndrome

Noonan syndrome (NS) is a relatively frequent autosomal dominant disorder characterised by facial dysmorphic features, heart defects, developmental delay, and short stature. This syndrome is mostly caused by gain-of-function mutations in the PTPN11 gene, encoding tyrosine phosphatase. The best-defined consequence of NS-causing mutants is an enhancement of Ras/MAPK activation that ...

Natural History of Noncirrhotic Portal Hypertension

Noncirrhotic Portal Hypertension (NCPH) includes a spectrum of chronic liver diseases characterized by increased pressure within the portal circulation in the absence of cirrhosis. The complications from NCPH are similar to that of cirrhosis induced portal hypertension which includes the development of gastrointestinal varices, portal hypertensive gastropathy, splenomegaly, sepsis and ...

Phase N/A

Pathogenetic Basis of Aortopathy and Aortic Valve Disease

Thoracic aortic aneurysm (TAA) is a type of aortopathy describing dilation of the proximal aortic dimensions including the aortic root, which is a risk factor for aortic dissection and sudden cardiac death. TAA and other forms of aortopathy (e.g. aortic tortuosity or aortic hypoplasia/stenosis) develop in the presence or absence ...

Phase N/A

Study to Assess Long-term Effectiveness of Zomacton and Treatment Adherence in Patients With Growth Hormone Deficiency or Ullrich-Turner Syndrome

Assessment of long-term effectiveness of ZOMACTON in treatment of Growth Hormone Deficiency or growth retardation due to Ullrich-Turner Syndrome and assessment of compliance and adherence, optionally with the aid of an electronic app or patient diary.
